What's the Magic Moment for Uber?

I love the notion of an aha moment. That's obviously going to be different for different companies, depending on what your product is. Can you talk me through how you go about deciding what that aha moment is and also is it one or is it aha moments plural? Well, I think it is plural, but maybe drawing on kind of my experience from Uber, you know, when I joined Uber, it was 2014,. The aha moment and how we thought about it was what was that point where we like created magic for the user.
